BUEF FOR POLISHING SPOONS AND OTHER ARTICLES.

Specificationforming part of Letters Patent No. 3,380, dated December 15, 1843; Reissued October l 7, 18 56, No. 399.

To all whom it may concern:

Be it known that I, LUTHER BOARDMAN, of East Haddam, in the county of MiddleseX and State of Connecticut, have invented an Improvement in the Manner of Forming Circular Buffs of Leather forthe Polishing o-f Spoons of Britannia Metal and other Articles of Like Character; and I do hereby declare that the following is afull and eXact description thereof.

I take thickleather which is so tanned and dressed as to be of a soft texture adapted to the making of polishing buffs, and this I cut into circular pieces of the size required, say from two or threeinches to a foot in diameter. These circular pieces I place together so as to make the required thickness for the buff, say from one to two inches. I then stitch them together at the distance of an inch, more or less, from their edges, by a row of stitches forming a circle,

leaving the respective pieces loose in every other part. Through the center of the buff, thus formed, I make a hole to receive a spindle, adapted toa polishing lathe, securing the bull" to said spindle in such manner as that itshall not turn thereon. The buffs thus formed have the pieces of leather of which they are formed perfectly free from each other excepting when they are united by stitching, and i in consequence thereof they operate very differently from such as have the respective pieces of leather of which they areformed joined together by glue, or other cement, or forced together by unyielding heads. These disks of leather will yield at the edges, will adapt themthe leather together,

selves more perfectly to the form of the article held against them, than when made in any of the modes heretofore adapted. The polish effected by them is more rapidly produced, and is moreperfect, anycoarse particles in the polishing substance bedding itself into the yielding buff.

It is necessary in using such buffs, to give to them a very rapid motion, as the centrifugal forcethus generated keepsthe edges of I while it does not pre vent that yielding which is necessary to their proper action. i

In the accompanying drawing A, A, are two such bufls of leather, upona spindle B.

The stitching by which the circles of leather are united are seen at C, C. The whirl D, may receive a band to give motion to the buffs.

Havingthus fully described the nature of my improvement in themanner of form-c ing circular buffs of leather for polishing spoons, or other articles, whatI claim there in as new, and desire to secure by Letters- Patent, is

The uniting of the pieces ofleather com- V posing the buff, by stitching them toeach: other, at aflproper distance from their outer of cement, o-runyielding substance; the same bemgeffected 1n the manner, purpose, hereln fully set forth.
